The invention belongs to the technical field of train control, and in particular relates to a train control data transmission method and system based on one-way broadcasting. The train control data transmission method includes: the station data server obtains the train control data, compiles the train control data into a first wireless message, and sends the first wireless message to the ground safety broadcasting system; the ground safety broadcasting system acquires The first wireless message sent by the station data server, transcoding the first wireless message into a second wireless message; the ground safety broadcast system adopts a one-way broadcast method to send the second wireless message to the train secure communication system. The train control data transmission system proposed by the present invention adopts one-way communication. The data transmission process is optimized, the timeliness and accuracy of train control data transmission are improved, and the operating cost and construction difficulty are greatly reduced.
Description
technical field [0001] The invention belongs to the technical field of train control, and in particular relates to a train control data transmission method and system based on one-way broadcasting. Background technique [0002] At present, EMUs equipped with CTCS-3 train control on-board equipment (ATP) can only run on CTCS-2 or CTCS-3 track lines, and they do not have the conditions to run on normal speed lines (CTCS-0 level) . If the ground equipment of the high-speed rail line fails, the EMUs equipped with CTCS-3 train control on-board equipment cannot run safely on the track line, nor can they bypass the normal speed line (CTCS-0 level), which affects transportation efficiency . [0003] In order to solve the above-mentioned problems in the existing technology, the existing CTCS-3 train control system adopts the two-way communication mode of the railway integrated digital mobile communication system (GSM-R) to realize the train control data transmission between the gro...
